Bit Rates

When comparing the bit rates, it's evident that as it gets smaller and smaller, the sound quality is affected and the whole piece sounds worse. The first two versions had high bit rates of 320 kbps and 192 kbps, and it was hard to notice any differences or flaws with them. Based on this, I can assume that high bit rates in general work well for audio, and you only start to have problems when you go lower than a certain point. This theory was supported in the versions of the song that were 96 kbps or less, because they gradually sounded more muffled, and as if a poor recording of the song was playing. I don't think that bit depth has an effect on sound quality because they all had 32 bits, but another difference was observed in file size. Those versions with high bit rates also required large file sizes, so a good use of thumb is the less bit rates you use, the less file space you'll need to have.
